Me and my bf have been dating about 6 weeks now. He lost his vaginity to me , but he's never been able to finish inside me like by vaginal sex. He can can only finish using his hand. Now I know he's new to sex but I've never exsprinced  this and if I'm honest I thought might happen and just to go with the flow but it seems now he'd rather just use his hand instead of trying to get to that point if that makes sense. It's making me feel a little in adequate. One of my friends suggested getting him to not do anything sexual for a week and try that, anyone else got any ideas ?
